Grow bags for potatoes are an excellent solution for patio or small space gardeners. You can purchase them right from our store. Learning how to grow potatoes in a bag will provide a space-saving solution, and it’s a fun family project.
The bag lets the plant spread out its roots and you can still add layers of soil. The reason for layering is the same as hilling. Potato tubers send out roots at the eyes, which branch out in soil. The more you cover the top of the root zone, the more roots they send out. More roots equal more potatoes. Using potato grow bags allows you to control the region the tubers are planted in and makes them easy to harvest. The spuds will be confined to the bag so all you need to do is dig around to find them.
Lift up the front flap of our bags for a more convenient way of harvesting below ground growing vegetables.
1. Fill the bottom with a couple of inches (5 cm.) of soil and compost mix and plant your seed potatoes. Fill with just enough medium to cover the tops of the tubers. Keep the soil mix evenly moist and cover the sprouted potato greens with compost mix as they come up.
2. Keep them covered with soil as they grow and as the soil level rises. Once the soil is at the top of the bag, allow the plants to flower and die back and then dump out the contents so you can pick through and get all the spuds. You can also harvest young spuds early in the process.
Note: I cannot express this enough keep them covered always with soil :)
3. Situate your bags in full sun and keep the soil evenly moist but not soggy. Keep an eye out for pests, especially chewing insects which can affect the vigor of your plants. Occasionally unearth a small tuber and check for any damage to the young potato. If you use clean new compost, you are unlikely to have any major soil borne insect problems.
4. Start harvesting as soon as you have little potatoes for tender spuds on the grill.
5. By fall, remove all the spuds to prevent them from freezing and splitting OR bring inside where it is warmer.
Note: As long as you have good lighting you can grow them inside :)
Potatoes are usually harvested within 6-7 weeks.
Hope this is helpful. If you have any other questions for us, we'd love to hear them :)
